产品介绍 | Galactose oxidase oxidizes galactose and some galactose derivatives in both free and polymeric forms. Oxidation occurs at the C6 position. The enzyme has a molecular weight of 68 ± 3 kDa, and the optimum pH is 7.0. |
备注 | Supplied as a lyophilized powder containing sodium phosphate and sucrose as stabilizers. |
生化机理 |
Galactose oxidase catalyzes the coversion of D-galactose to D-galacto-hexodialdose. 2-Deoxy-D-galactose, lactose, melibiose, raffinose and stachyose react with galactose oxidase in the peroxidase:o-tolidine system. Essentially no oxidation of D-glucose, L-galactose, L-arabinose or D-glucuronate has been observed. |
